How to identify layer within group in ArcGIS Pro

Hi All,

I am struggling to identify a layer within a group and create that object for my script.

This would be the script line I follow to create an object for just a 'standard' layer:

road_ln = map_generic.listLayers("Road")[0]

If I were to do the same for a layer within a group layer, I identify the following structure as below

Network/Road

... with Network being the Group Layer and Road the Layer within that specific group.

Following this logic, I then go and try the below without success:

road_ln_grp = map_generic.listLayers("Network/Road")[0]

I have been going through documentations and the community these past days.

Any idea how I am able to do so?

Check the code provided in this thread:

@FC_Bassonprovided this example:

proj = arcpy.mp.ArcGISProject('CURRENT') m = proj.listMaps()[0] ml = m.listLayers() for l in ml: if l.isGroupLayer: print(l) lyrs = l.listLayers() for lyr in lyrs: print(lyr)
